top left and the film rewinding crank at the bottom right of the camera body (instead of the cocking lever being at the top right and the rewind crank at the top left). The cartridge sits in the right side of the camera and correspondingly the exposures lay "upside down" on the film, reflected by the inverted position of the film inscriptions (type, frame numbers) of under/over landscape pictures. To change the film, the back must be slid downwards and removed fully, like on the Contax, for example. Light meter For the shutter-coupled exposure meter of the prototype camera, Waaske selected a selenium cell powered meter from . The manually adjusted exposure control remained unchanged in later models of Rollei 35. On the way to mass production When Heinz Waaske finally presented the fully functional new camera prototype to his employer, Heinrich Wirgin (a.k.a. Henry Wirgin) said: "So you have wasted time on your own construction in my prototyping workshop?!". It was not until that moment, that Wirgin told his chief engineer that he had already decided to end camera production and photo equipment business. Looking for new employment, Waaske presented his compact camera to Ludwig Leitz and to Kodak, but to no avail. In January 1965 Waaske started working for Rollei in Braunschweig (Brunswyck). Having become Rollei's managing director only in March 1965, Heinrich Peesel accidentally got a first glimpse of his new employee's tiny prototype camera. Filled with enthusiasm, Peesel decided that the camera should immediately be further developed by Waaske for mass production, but, using only parts of Rollei's suppliers. Waaske's little camera was presented at photokina in 1966 as Rollei 35, with a better lens – the Zeiss Tessar 3.5/40mm lens, a state-of-the-art CdS-exposure meter and a precision-made diaphragm shutter made by Compur, using Waaske's patented shutter design. The Rollei 35 standard model Development The camera had to be converted to use parts from Rollei's suppliers, as Rollei did not maintain business relations with Metrawatt and Steinheil. A high-quality Tessar lens was made by Zeiss. Rollei's light meter supplier was Gossen. Whether to use either a photovoltaic selenium sensor or a CdS photoresistor, was finally decided in August in favour of the CdS. Gossen named the same measuring range for both solutions. A selenium-cell powered light meter was cheaper in production and did not need a battery. However, the much smaller CdS-photoresistor improved the stylish look
